Claims. (01. 141-9) My invention relates to improvements in washing machines, the object'of which is to provide a washer which is capable of use for washing clothes or washing dishes, glasses and the like. effect on clothes by pulsating the water intermittently through the body of the clothes, so that no violent clothes disturbance takes place and that the clothes are not rubbed against themselves or the basket in which the washing takes place. A further object is to provide means whereby a relatively small amount of hot water. is required for washing dishes and the washing is effected either by pulsation or by throwing water up and around the contents of the basket while imparting slow rotation to said basket.

The invention consists essentially of a washing receptacle having a flexible water bag in communication therewith and means for compressing the bag to force its water content into the washing receptacle, as will be more fully described in the following specification and shown in the accompanying drawing, in which:

Fig. 1 is an elevational view of the invention.

Fig. 2 is a plan view.

Fig. 3 is a transverse sectional view of the invention taken on the line 2-3 of Figure 2 showing the clothes washing basket. v

.Fig. 4 is a transverse sectional view taken on the line 44 of Figure 2 showing the dish washing basket and the valve Jet structure.

Fig. 5 is a fragmentary view of the valve iet structure optionally usable in dish washing;

In the drawing like characters of reference indicate corresponding parts in each figure.

The numeral I indicatesa cylindrical washer or tank having side walls 2, a fianged upper rim 3 and a bottom wall 4. Formed in the side wall 2 adjacent the bottom wall I is a rectangular opening 5 which provides communication be-.

tween the tank I and ;a flexible water bag C.

The water bag 6 is preferably of rubber and is arcuate in plan to lie in substantial contact with the wall 2 andis'of greater length than the opening 5. The bag is set in horizontal posi tion so that water poured into the tank will enter freely into the bag to 1111 it.

Mounted from the wall 2 is a motor I preferably having an inbuilt reduction gear, not shown, and a drive shaft 8, which shaft is provided with a worm 9 meshing with a worm wheel l0 upon a vertical shaft II. The drive shaft 8 is fitted with a suitable coupling l2, to which a flexible shaft and rotary brush, not shown, may

Another object is to produce the washing a be attached for cleaning out pots and pans by mechanical means.

A crank disk M is secured to the base of the shaft H which is connected through a connecting rod II to a swinging arm IS. The swinging 5 arm is pivotally mounted on a pin I1 and is car- 'ried between upper and lower bearings I8 and I! which extend from the tank wall 2. To the free end of the arm IS a thrust plate is piv- .otally-connected which bears against the water 10 bag 6 to collapse itand cause the water to surge from the bag to the tank.

Mounted upon the upper end of the shaft ll is-a crank disk 2| having a crank pin 22 upon which a pawl 23 is mounted. v".li'his pawl is proin vided with a leaf spring 24 which bears against an abutment 25 for the purpose of holding the pawl up to its work.

The tank I is provided preferably with two\ baskets, one for dish washing which is generally 20 indicated by the numeral 26, and one for clothes washing which is generally indicated by the numeral 21. The device as shown in Figures 1 and 4 is fitted with the basket 26.

The basket 28 is. a wire structure having any 26 desired form of racks or devices, not shown, for thepurpose of supporting crockery and glassware in a convenient position for washing. The basket 26 is provided with a peripheral rim 28 which is adapted tobear upon the rim-3 of the 80 tank I and to rotate thereupon. The rim 28 is provided with ratchet teeth 29 which are progressively engaged by the pawl 23 as the crank disk 2| rotates to impart intermittent rotation to the basket within the tank. 85

The basket 21 is preferably of sheet metal, having a perforated bottom wall 3| and upper and lower rows of perforations respectively numbered 22 and 33 in its side walls. A soft rubber gasket 3| surrounds the lower periphery of the basket to cause the water to pass through the apertured bottom wall 3| Demountably secured about the opening 5 in the tank wall is a valve jet structure 36 consisting of a plate 21, see Figure 5, having an opening 30 substantially conforming to that of the opening I. The opening 38 is divided by vertical ribs which pivotally support a series of channel shaped flaps 40 on a pin ll which is disposed approximately one-third of the distance from the upper edge of the flaps, so that as the water bag i is distended the flaps are swung by the water flow thereto into a substantially horizontal position, thus providing a free water passage from tank to water bag. when the water bag is collapsed, the flaps ll assume their substantially vertical position and the water from the bag is forced upwardly in a series of jets at relatively high velocity and substantially in the direction indicated in dotted line as at x in Figure 4, to wash the crockery 1 1! in the basket 26. When this valve jet structure is used, a small amount oi water only is required to wash the contents of the basket.

When using the device for dish washing, the articles to be washed are placed in the basket 26 and preferably the valve jet structure 38 is put in position. Hot water is put into the tank to the height of the bottom of the basket and the motor is'started, which causes the bag 6 to be alternately collapsed or squeezed and to fill with water from the tank. Water is thrown upwards through the basket to wash the contents on each squeezing of the bag and is returned to the bag as the thrust plate is moved away from -the side of the tank. Following each spurt of water upwards into the dishes, the pawl 23 engages a tooth 29 of the basket rim 28 and moves thebasket rotationally upon its vertical axlsQso that the water from the valve jet structure will strike the contents of the basket from a diflerent lateral angle at each spunt.

When using the device for washing clothes, the basket 21 is preferred and the valve jet structure is removed. The clothes are placed in the basket and are preferably held against inflation by placing a foraminous cover'fl upon them. On the reciprocation of the thrust plate 20 and the surge of water through squeezing of the water bag and the tank, the water will be urged through the clothes-upwardly and as the bag is distended the water willg-ravitalte again through said'clothes to wash them. The clothes will not be materially disturbed, consequently there will be no wear due to washing action.

; What I claim as my invention is:

1 1. A washing machine comprising a tank having an opening adjacent its base, a water bag connected with said tank and adapted to be supplied I amaass with water from the tank through saidopening, a valve structure interposed insaid opening for admitting water to the bagto substantially the full bore of the opening and for diverting the water in an upward direction from the bag to the tank as the bag is compressed.

2. A washing machine comprising a tank having an opening adjacent its base, a water bag connected with said tank and adapted to be supplied with water from the tank through said opening, a valve structure interposed in said opening for admitting water to the bag to substantialiy the full bore of the opening and for restricting the opening and diverting the water in an upward direction from the bag to the tank as the bag is compressed. n

3. A washing machine comprising atank having an opening adjacent its base, a water bag communicating with the tank through said opening, a shaft, an arm haying a thrust plate, adapt-- ed to engage the bag, .a driving connection between the shai't and the arm, said connection consisting of a crank upon the shaft and a connecting rod extending from the crank to the arm to impart reciprocaltory movement to the thrust plate and compress the water bag against the side offthe tank.

'4. A washing machine'comprising a tank having a peripheral wall and an opening at the base of the wall, a bag mounted on the outside of the tank and in communication therewith through said opening, and means for collapsing the bag against the peripheral wall to force water from the bag to said tank.

5. A washing-machine comprising a tank having a peripheral wall and -anelongated horizon-' tal opening at the base or said peripheralwall and a horizontal 'bag mounted jentirely outside the tank and inv communication therewith through said opening, and means for collapsing the bag against the peripheral "wall to force water from the bag to said' tank.
